Definitions:

Break-Even Points

The production level or point in sales at which total revenues equal total expenses, resulting in neither profit nor loss.

Shutdown Point

The level of operations where a company's revenue from goods or services sold just covers its variable costs, beyond which it becomes more cost-effective to halt production.

Short Run

A period in which at least one input, such as plant size or capital, is fixed and cannot be varied to change output levels.

Long Run

A time frame in economics where all inputs and costs are variable, allowing for full adjustment to changes.
